CARDIN G-MACHINE.

Specification of Letters Patent.

Patented Oct. 31, 1916.

Application filed July 2, 1914. Serial No. 848,617.

To all whom it 'mdy concern Be it known that I, ROBERT S. IVALLAGE, acitizen of the United, States, residing at F itchburg, in the county ofWorcester and State of Massachusetts, have invented certain new anduseful Improvements in Carding-Maehines, of which the following is aspecification.

My invention relates to an improvement in carding machines, and theobject is to provide a fly or waste roll for receiving the waste thatmay be thrown out between the licker-in roll and the cylinder or swift.

The invention relates to still other novel features of construction andcombinations of parts which will be hereinafter more fully described andpointed out in the claims.

In the accompanying drawings: Figure 1 is a view in top plan of aportion of a carding machine showing the manner of locating theinvention; and Fig. 2 is a detail view in elevation showing the mannerof mounting the improved fly or waste roll. Fig. 3 is a section throughthe licker-in, cylinder and fly rolls.

A represents the frame of the carding machine, upon which is mounted thelap roll 1. The feed roll 2 is mounted in advance of the lap roll. Alicker-in roll 3 is mounted on the frame in advance of the feed roll.The pulley 4 is mounted on the licker-in roll whereby power may betransmitted thereto. The feed roll and lap roll are connected togetherby means of a belt 5 passing over pulleys 6 and 7 on the rolls 2 and 1respectively. The feed roll is provided with a large bevel gear 8, whichis driven by a shaft 9 which is provided with a beveled pinion 10, whichmeshes with the bevel gear 8. Located adjacent to the lickerin roll isthe large cylinder or swift B. A cover or housing 11 is mounted over aportion of the licker-in roll 3, and mounted in brackets 12 connected tothe housing is a fly or waste roll 13, which is provided with a largefriction wheel 14, which meshes with the friction wheel 8, transmittingpower thereto. As the cotton is drawn into the machine by the licker-inroll, it is taken upor seized by the large cylinder B, which revolves ata much higher speed.

The filaments which are seized and carried by the cylinder B are teasedor drawn out of the teeth of the cylinder by the roller C, which movesmore slowly than the lickerin roll 3, and picks the neps off thecylinder. These neps are carried around by the roller 0, and are caughtby the lickcr-in roll, which presents them again to the cylinder B withfresh material from the lap.

The method of carding is the same as that pursued with carding machinesin general.

use, as the filaments which are drawn from the end of the lap andconducted by the licker-in roll to the cylinder, there is a tendency forthe filaments to fly or be thrown out, and by placing the fly roll 13 ina position between the cylinder and licker-in roll so that the filamentswill be caught thereby, a great saving will be made by the roll catchingthe filaments which are not taken up by the cylinder. The roll 13 isdifferent from the ordinary stripping roll, because it is not intendedfor such a purpose, but is merely located in such a position between thecylinder and licker-in roll that it may catch any of the filaments ormaterial that may H or be thrown between said cylinder and lie er- 'thatmay issue therefrom without interfering with the operation of thecylinder.

3. In a carding machine, the combination with a cylinder and licker-inroll, of a housing over said licker-in roll, and a fly roll movablymounted upon said housing to receive the fly that may issue from betweensaid licker-in roll and cylinder.

4. In a carding machine, the combination with linder and licker-in roll,and a re mov. t i roll located in a position between the h cr-in andcylinder rolls to receive the waste or fly that may issue from betweensaid cylinder and licker-in rolls, said fly roll adapted to move awayfrom said rolls as the circumference of the fly roll increases by theaccumulation of the waste or fly thereon.

5. In a carding machine, the combination with a cylinder and licker-inroll, of housings over each roll, having an opening formed between theiradjacent ends, and a Hy roll mounted on one of the housings and inengagement with each housing for collecting the waste or fly that issuesthrough th opening between said housings.

(i. In a carding machine, the combination with a cylinder and alicker-in roll, of housings over each roll having an opening formedbetween their adjacent ends, a fly roll mounted on one of the housingsand in engagcment with each'housing for collecting the :te o1- flv thatissues through the opening; between the housings, power means, and meansconnected to the fly roll in engagement with the power means fortransmitting mo tion to the fly roll, said roll adapted to move 1 utwardas the circumference of the roll increases by the accumulation of thewaste thereon, and means for governing said move ment of the roll andmaintaining the traction means inengagement with the power means.

7. In a carding machine, the combination of a lieker-in roll and acylinder, and rotatable removable means located in a position betweenthe licker-in roll and cylinder to receive the fly that may issue frombetween said cylinder and licker-in roll.

8. In a carding machine, the combination of a licker-in roll andcylinder, and positively driven rotatable means located in a positionbetween the licker-in roll and cylin- Copies of this patent may beobtained for five cents each, by addressing the Commissioner of Patents,Washington, D. C.
